The Chinese search engine Baidu was briefly defaced earlier today. The replacement page was identical to the defacement in a recent twitter.com hack. It appears that like in the Twitter case, the attacker did not attack the site itself, but instead changed the sites domain registration. This kind of attack is not new, but still quite successful. To defend against this attack, companies should review domain name registration policies and how credentials are handled. Changes to the registration are typically infrequent. In addition to the domain name registration itself, DNS has been tampered with by stealing credentials to admin interfaces of DNS services and internal DNS administration utilities. It is also worthwhile to monitor DNS zones for changes by regularly polling ALL authoritative name servers.
